Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM ) is a rare condition of uncertain incidence given its likely underdiagnosis. PTTM has been described most frequently in association with gastric adenocarcinoma, but other primary malignancies have been identified. The prognosis of PTTM is very poor, and patients often die within days or weeks of diagnosis. There are, however, several medications currently being used with unknown therapeutic benefits. The case presented below describes a patient with PTTM and esophageal adenocarcinoma, which may be the first report of its kind. One other case of esophageal cancer associated with PTTM was found in the literature review, but it is of squamous cell carcinoma histology. Herein, we report a case of a male with rapidly progressive pulmonary hypertension and right heart failure who, in the course of treatment/evaluation, was found to have esophageal adenocarcinoma. While early diagnosis may not alter the course of the disease, antemortem diagnosis may identify better therapeutic options and better inform patients of their prognosis, allowing them to maintain autonomy in their medical decisions.
